This invention relates to a device for dispensing material such aspowdered soap and other fluent products.

An object of the invention is to provide a 3 device for dispensing alimited quantity only of the dispensable material upon each operation ofthe actuating means.

Another object is to provide such a device having means associatedtherewith for precluding leakage and wastage of the dispensablematerial.

Another object is to provide a dispenser having novel valve meansassociated therewith.

Another object is to provide such a device which is simple and efficientin construction and operation.

rlhese and other objects are attained by the means described herein anddisclosed in the accompanying drawing, in which:

Fig. 3 is a. cross-sectional view taken on the $0 line 3-3 of Fig. 1. j

The dispensing de'vice comprises a container having a body portion 1,preferably cylindrical in form, a lower .portion 2 slanting inwardly ofthe body, and a lower portion or neck 3 of a reduced cylindrical shape.In the upper portion of the body 1 a bearing strip 4 is securedtransversely of the center of said body. This strip may be provided withside flanges 26 for purposes of reinforcement. At the center of saidstrip is provided a transverse slot 5 which continues through one of theflanges 26 for the purposes to be described and opening upon one edge ofsaid strip. A retaining plate 6 is remov- 5 ably attached upon thecentral portion of strip 4 and is provided with a slot 7 adapted toextend oppositely to the slot 5 for-provid lng the aperture 8. A pushrod 9 has its upper end slidably positioned in the aper ture 8, thelower end of the rod projecting 5o outwardly of the reduced portion orneck 3 of the container and being provided with a button 10. Adjacentits upper end, the rod 9 is formed with a shoulder 11 adapted to abutthe underface of strip 1 for limiting up- 55 ward movement of the pushrod. At the extremity of its upper end, the rod is provided4 with anabutment 12, such as a nut, which limits downward movement of the pushrod.

A coil spring 120 is positioned upon the rod 60 between the strip 4 anda wire fork member 13 secured to an intermediate portion of the rod asat 14. The spring 120 normally urges the rod to its lowermost position.The Jfork member 13 is adapted'to stir up the contents a5 of thecontainer upon rotation of the rod 9 on its longitudinal axis.

1n the neck -portion 3 of the container is positioned a pair of valveseats 15 and 16 respectively. Upper valve seat 15 may consist 70 of acircular stripl attached along one edge to the inner face of neck 3 andhaving the body thereof bent inwardly of the container to provide theinwardly projecting valve seat shown. The lower valve seat 16 may con-75 sist of a strip having one longitudinal edge secured to the innerface of neck 3 and the remainder of its body 18 formed to projectinwardly of said neck to provide the lower valve seat. The bottom edgeof neck 3 may be ren- 80 dered smooth by curling as at 17. The free edgeof the seat 16 may be further bent inwardly of the neck 3 as indicatedat 19.

Upon the rod 9 are provided an upper valve 20 and a lower valve 21adapted to coop- 85 erate with the upper and lower valve seatsrespectively. Both of these valves provide preferably downwardlydivergent outer surfaces as shown. In addition the edge of the lowervalve may be formed with a slightly downwardly -upon ared portion 22adapted to seat snugly against the inwardly turned portion 19 of the cooerating valve seat.

llig. 2 lllustrates the normal non-dispensmg position of the device ofthis invention. It will be seen herein that the association of thevalves with their respective valve seats is such that when the lowervalve 2l is sealed against the valve seat 16, the upper valve is openfor permitting a limited quantity of the dispensable material to enterthe space between the upper and lower valves. By reference to Fig. 2 itwill be seen that when the push rod 9 is actuated upwardly, the uppervalve 20 is closed for precluding downward passage of the dispensablematerial thereabove. It will further be seen that when theI upper valveis closed, the lower valve 21 is open for permitting dispensing of thelimited quantity of fluent material held between the valves asexplained, It will be seen that no matter how long the push rod is heldupwardly, no further dispensing of the material will be effectedinasmuch as the upper valve at this time remains continuously closed.Hence it is necessary to actuate the rod successively in order to eiectfurther dispensing whereby wastageof the material is prevented. Thespring 120, as above mentioned, normally urges the push rod downwardlywhereby the lower valve is held closed. The peculiar formation of thecooperating free edge portions of the valve 21 and its seat 16, is suchas to eifect an eiicient seal against leaking of the material from thecontainer. The top of the body portion 1 of the container may beprovided with a removable lid b 23 to which one end of a chain 24 may beattached, the other end of the chain being secured to the body portionof the container, or as shown, to the uppermost of a pair of supportbrackets 25 secured in alignment upon the body of the container andadapted to be secured to a supporting surface for holding the dispensingdevice in its proper vertical position.

It will be seen by reference to Fig.` 3 that the push rod 9 may be movedlaterally out of position for permitting removal or replacement of thespring 120 or the fork member 13. This arrangement and cooperat on of`the push rod and the plate 6 likewise has to do with the assembling ofthe dispensing device. In assembling the device, the button 10, whichmay have a threaded connection with the end of the push rod, may beremoved. from posltion. The rod, with the valves 20 be and 21 previouslysecured thereon and the fork member 13 in place, may be inserteddownwardly through the body portion and thel neck portion of thecontainer. The sprlng 120 is now positioned and depressed the rod 9until the top of said rod has been slipped into the slot 5 providedinthe cross strip 4. The spring is held depressed until the retainingplate 6 and the nut or abutment 12 have been properly placed in positionas'indicated in Fig. 1. The valve seat 16 may now be slipped overthevlower end of the rod 9 and secured in cooperatingl relationship withthe lower ing said valve seat in the y described and illustrated.Thereafter the button 10 may be replaced upon the rod and the dispensingdevice is in readiness for positioning anduse.
